Magnet


Magnet is something that can attract metallic object and repel other magnets, it also produces magnetic field.
Magnets have two poles, they are called north and south, they both attract iron,cobalt, but they repel each other, but if a different pole meet each other than they will attract. Magnetic field is the field or the area that appears when a magnetic force is happening, Electric Field is the field or the area that appears when there is an object that has an electric charge in it. An Electromagnet is some kind of a magnet in which the magnetic field is produced by an electric current

Electricity Experiment

For the past 3 days me and my class did a little experiment, it was an experiment related to electricity, electrons, and SCIENCE!!, we created a parallel and a series circuit, soo the materials that we use are, some AA batteries at least you must have 6, 1 or 2 meter wire, a wire clipper, a lighter, some tiny light bulbs at least 3,  tape, and 2 pieces of infra board.

what we did for the series is that we tape 2 batteries, use the lighter to get the thin copper inside the wire, connect the copper to the end of the battery, and connect it to another wire that is connecting to a tiny light bulb that is connecting to the other side of the battery, and then tape all of them into the infra board, press both copper wire that is connecting to each side of battery, and... voilà!! the light bullb turn on!

for the parallel it's basically the same, the only difference is that we the middle part of the wire, making it into 2 pieces, and burn the 2 pieces of wire to get the copper, and connect it to 2 tiny light bulbs

AC and DC

in and electrical current, there is something called Alternating Current (AC) and Direct Current (DC)

AC or Alternating Current is a current that flows in a different direction, or in the opposing direction

DC or Direct Current is a current that flows in the same way

some examples from them is that,switches that are from walls, like a refrigerator, washer, lights, and ovens are AC and electronics that are powered by a battery like a cell phone, flashlight are DC

Potential Difference, Electric Current, and Electric Resistance

In an electrical circuit the the electrons from the battery moves around the circuit, when an electron pass through a light bulb in the circuit they lose some of the electrical energy making the lamp to lit up, therefore across the lamp there is an electrical energy difference, electrons that are entering the lamp have a higher electrical energy than the one leaving the lamp, this difference in electrical energy on lamp is called "Potential Difference" or "P.D".

The crash or the bump of electrons and wire in an electrical circuit, making it harder for the electrons to flow properly in an electrical circuit are called Electric Resistance.

The flow of electrons in an electrical circuit are called Electric Current

Volts (V) is a measuring unit used by Potential Difference, Potential Difference is also measured using a Voltmeter

Amperes (A)  is a measuring unit used by Electric Currents

Ohms (Ω) is a measuring unit used by Electric Resistance

Static Electricity

In this world, almost everything is made out of Atoms, Atoms are the basic building block of matter, and Atoms are made out of 3 things Protons, Electrons, and Neutrons each of them has their own properties Proton have a positive charge, Electrons have a negative charge, and Neutrons are neutral or no charge.
Today, me and my group do an experiment in class, we rub a plastic folder into someone's hair, shirt, pants and then we try to hover the plastic thing on tiny pieces of paper and sharpener waste, what happen is that the tiny pieces of paper and the sharpener waste stick to the plastic thing. and that is because, that plastic thing gains electrons from the thing we rub on (hair,shirt,pants) making that plastic thing negatively charge, making the tiny piece of paper and the sharpener waste attracted to the negatively charge plastic thing because the tiny piece of paper and the sharpener are full of protons and positive charge.

In an electrical circuit the cell or battery pushes the electrons around the circuit, when an electron pass through a lamp in the circuit they lose some of the electrical energy making the lamp to lit up, therefore across the lamp there is an electrical energy difference, electrons that are entering the lamp have a higher electrical energy than the one leaving the lamp, this difference in electrical energy on lamp is called "Potential Difference" or "P.D". Potential difference is measured in units called "Volts" and has the symbol V it is also measured by something called a Voltmeter

Electric current is the movement of electrons from the negative terminal to the positive terminal of a circuit. This is because electrons are negatively charged and want to move away from the negative terminal and head towards the positive terminal,that is called "Conventional Current Flow"

Introduction

Hey,
I'm a student from Highscope Bintaro, i am currently in grade 8, my hobbies are, playing games, listening to music, and many more. in this blog i will write about the things i learn in this term on science, this is a school project and i hope you will enjoy and like everything that i write here. Thank you, and please like my post
